As an entry-level SQL developer, your job is to use a structured query language to develop, test, and implement software for a company. Entry-level developers often help troubleshoot problems, provide support for senior developers, communicate with clients to understand their needs, and examine the existing code to look for ways of improving it. Many employers use this role as a type of extended training period, and you may work directly under the supervision of a more experienced developer. In some industries, such as healthcare, you may need to learn about and use uncommon file formats and systems to ensure compliance with federal privacy regulations.
